Flooding happens to everyone in this hobby. Thankfully my tanks are in the basement where I generally could care less if it floods. I have an ATO but needless to say if you turn off the ATO then move the ATO hose out of he sump to clean out a piece of equipment, remember to put the hose back into the tank before plugging the ATO back in
I dumped about 10g of water all over the carpet before I realized my stupid mistake
